PUBLISHED SEPTEMBER 30, 1969 673,959 a I 1', LINEAR POLYMERS OF2,2-DIMETHYL-5- AMKNOPENTANOLJ James Cuihbert Martin, Sarah Joelle Rush,and Russell Gilkey, all. of P.0. Box 511, Kingsport, Tenn. 37662 FiledOct. 9, 1967. Published Sept. 30, 1969 Int. Cl. C08g 17/06, 17/08, 17/13US. Cl. 260-77.5 No Drawing. 16 Pages Specification Highly polymericlinear condensation polymers are prcpared from2,2-dimethy1-5-aminopentanol-1 and at least one bifunctional carboxycompound or derivative thereof. Examples of carboxy compounds orderivatives thereof are cycloaliphatic dicarboxylic acid, cycloaliphaticdicar boxylic acid ester, aromatic dicarhoxylic acid, aromaticdicarboxylic acid ester, carbonic acid, and derivatives of carbonicacid. Exemplary is the product of the condensation of diphenyltcrephthalnte with 2,2-dimeihyl5-aminopcntanol-l in the presence ofdibutyi tin oxide. This and other products of the invention areamorphous, non-crysstallizable polymers possessing a low processingtemperature and a high use temperature. The polymers are useful iniheproduction of molded objects, sheeting and film. ,Q

The polymers also can readiiy be applied as hot-melt I I adhesives.
